Positive indications – studies and publications

Pipeline – Clinical studies

The purpose of the company’s clinical development program is to support the ongoing market introduction of the K.O.S technology for chronic migraine in the EU and lay the foundation for regulatory market access in other markets such as the USA.

Our clinical development strategy is aimed to conduct studies of specific nature and shorter duration ourselves, and to encourage and facilitate other independent external investigator-initiated studies once such opportunities arise.

Ongoing & Planned Clinical Studies

  • The randomized controlled PM007 study saw the last subject leaving the study at the end of July 2022. A manuscript for a scientific article will be submitted for publication at the end of October 2022 at the earliest. This study recruited approximately 132 subjects with chronic migraine and was conducted at nine clinics in Germany and Finland. the primary endpoint is the reduction of headache days. Sub group data (from the 97 German patients) was presented at MTIS 2022 in London.

  • The study on chronic rhinitis PR008 will complete the clean data file June 2022, whereafter analysis and publication work will follow.

  • The PM009 study is a planned, open pilot study to evaluate the efficacy of intranasal kinetic oscillation stimulation (K.O.S) in the preventive treatment of chronic migraine on subjects not responding to treatment with monoclonal antibodies targeting the CGRP pathway. The study aimed to include 25-30 subjects to investigate the reduction of headache days using the KOS technology. Blood samples will be evaluated for relevant biomarkers.
    The study is conducted at King’s College in London with three to four referring clinics assisting with the recruitment of suitable subjects for the study. The objective with this investigation is to detect a potential positive effect. Any level of positive result will likely mean a great opportunity for our company as this challenged patient group has very few options left.

  • The PM010 study is a planned, open post-marketing clinical follow-up investigation to follow long-term performance and safety of intranasal kinetic oscillation in subjects with chronic migraine during regular clinical treatment. The study will recruit 200 subjects and will be conducted at approximately 15 clinics in three to four European countries, the follow-up is 12 months. Data from this open study will be reported in intervals and used to fine-tune recommendations for the clinical regime.
